QUESTION 1 Global temperature trends can be inferred from changes in ________ and ________. fossils; chemical isotopes found in
kirza4 [7]

1. fossils and chemical isotopes found in sediments and glacial ice

By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.

2. decrease in mortality because winter is warmer

The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm.

Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.

3. all activities by humans affecting the Earth and its biosphere

Anthropogenic activities are all activities by humans affecting the Earth and its biosphere.

4. decline in sea ice

For three autosomal dominant genes, what is the probability that a cross between two heterozygotes (i.e. AaBbCc x AaBbCc) will p
Free_Kalibri [48]

Answer:

27/64 or 0.421

Explanation:

When AaBbCC X AaBbCc :

A_B_C_   =   27

aaB_C_    =   9

A_bbC_    =   9

A_B_cc     =   9

aabbC_     =   3

A_bbcc     =    3

aaB_cc      =   3

aabbcc      =    1

Out of the total 64 offspring, 27 will have at least one dominant allele for each of the three genes hence these 27 offspring will show dominant trait for all genes. So the probability of producing a dominant trait for all genes will be 27/64 or 0.421
